A standard telephone 10, with which the apparatus embodying thisinvention is particularly adapted for use, includes a base 11, areceiver and ytransmitter unit 12, and a finger-whecl-actuated impulsetransmitter 50 11i, which is of well known design and is be secured in1981. Serial No. 534,303.

characterized by a rotatable finger wheel or disc 15 provided with aplurality of fingerreceiving openings 16, corresponding to variouscharacters, both letters and numerals, to be selected in the dialing oftelephone numbers.

The apparatus, herein shown in association with the telephone10',includes a housing 17, adapted to accommodate therein variousmechanisms of the apparatus and to support thereon the telephone, whichmay lace by suitable clampin means, comprising, for example, a -pair ostationary abutments 18, and a movable clamp finger 20, which issuitably pivoted to the inner wall of the housing and is ada-pted to bemoved into clamping engagement with the base of the tele hone by apressure screw 21y carried by the ousing.

Suitably connected to the housing 17, as by a hinge 22, is a cover orcontrol panel 24 which carries a plurality of selective control buttonsor switches a to j, inclusive, and a plurality of individual controlbuttons or switches s, it being noted that there is but one row ofselective control buttons, whereas there are a plurality of rows ofindividual control buttons. As will hereinafter more clearly appear, theselective control buttons are employed singularlyone for each character,either a letter or a numeral, of a telephone number to be called; andthe individual control buttons are employed sin larly for the completecalling of recor ed telephone numbers to which they respectivelycorrespond. Each of the selective switches as well as each individualswitch includes a shank 25, mounted for vertical movement in a bearing26, secured to the cover 24, the shank being provided at its upper endwith a finger piece 27, of insulating material, which is provided with acuplike recess 28, adapted for the reception of the upper end of aspring 30, which is supported by the cover and is adapted to maintainits associated switch normally in opencircuit position. The lower end ofeach shank 25 is bent at an angle to provide an arm 31, adapted to slidein a roove or channel 32, formed in a depen ing guide 33,V

which is secured to the cover and cooperates with said arm to hold thecontrol button against rotation. To the arm 31 of each shank 25, issecured a horizontally disposed brush bar 34, which extends transverselyof the cover or cont-rol panel 24. Secured to the brush bar 34 of therespective switches a to j inclusive, is a contact finger 35. Thesecontact lingers are differently positioned, that is to say, they arelocated out of alignment with each other; and the reasonv for thisnon-aligned relation will hereinafter more clearly appear. To the brushbar 34 of each of the switches s, is secured a contact brush 36, whichis composed of a plurality of fine and more or less resilient wiresarranged in a row extending transversely of the cover or control panel24, each brush bein of a width much greater than the widt of the contactfinger 35, for the reasons which will hereinafter become apparent.

Carried by the housing 17 is an insulating base 27, directly above whichthe cover or control panel 24 is normally positioned. In the face ofthis insulating base, is embedded a plurality of contact bars al to jl,which correspond to the control switches a to j, inclusive. Alsoembedded in the insulating base 37 are a pluralityv of groups of contactbars 81 to an, inclusive. All of the contact bars, a1 to jl and s1 to811, are arranged in a parallel relation with their upper faces eX sed.Considering Fig. 6, it will be noted t at the contact bars al to jl,inclusive, are respectively connected to the several contact bars 82 to811, inclusive, by conductors 40 to 49 inclusive. All of theseconductors, as will be understood from Fig. 5, pass through a protectiveconduit 50 and lead respectively to a plurality of commutator brushes 51and 60, located within the housing Where they are held in a spacedrelation by an insulating support 61, suitably connected to the housing17.

Referring again to Fig. 6, it will be noted that the several contactbars 81 are connected together by a conductor 62, which, as shown inFig. 8 is connected to one of the armature brushes of a motor M,employed as a driving unit for the apparatus and suitably supportedwithin the housing 17. This motor may be connected to 'an ordinary houselighting circuit through leads 64 and 65, between the latter of whichand the conductor 62 is disposed a switch 66. This switch 66 is of asuitable manually actuated type and may be conveniently carried by thecover or control panel 24, immediately above the row of selectivebuttons or switches a to j. Connected across the armature of the motorM, is the primary winding 67 of a stepdown transformer 68, which issuitably supported within the housing 17. The secondary Winding 70 ofthis transformer is grounded to the housing 17, as shown at G, and isconnected at its other end,

by a conductor 71, to the conductor 65, from which a branch conductor 72leads to and is connected to the cover or control panel 24,

ceive the end of a trip lever 79, connected to a` sleeve 80, ournalledon a trunnion 81 which is secured to the housing 17. Connected to v thesleeve 8O is a trip arm 82, to the outer end of which is connected a.thrust link 84. This thrust link is suitably connected to the upper endof an oscillatory shaft 85, carried by a bearing hub 86, mounted on astationary shaft or pin 87, suitably supported by the housing 17, theshaft being adapted to move under the influence of the overnor 76 to theright or left, as viewed in Fig. 5, about the shaft 87 as an axis. Onthe shaft 85 is mounted a sleeve 88, one end of which is rovided with aworm 90, and the other end o which carries a spur gear 91. The worm 90is adapted, as the speed of the motor is accelerated to engage asegmental gear 92, connected to a transverse shaft 94 suitablyjournalled in the side walls of the housing 17, and is adapted t-omoveout of engagement with that gear as the speed of the motordecreases. Upon engagement of the worm 90 with the segmental gear 92,the shaft 94 is rotated against the influence of a tortion spring 95carried by that sha-ft, one end bf such spring being anchored to thehousing 17 and the other end thereof being suitably connected to thegear 92. To the outer end of the shaft 94, is connected a spur gear 96,which meshes with a similar gear 97, carried by a transverse shaft 98journalled in the side walls of thelhousing 17. This latter gear mesheswith a rack 100, slidably mounted on the housing 17 and is provided witha plurality of pins 101, which project upwardly through elongatedopenings or slots 102, formed in one of the longitudinal margins of theinsulating base 37, the purpose of the pins 101 being to effect lateralshifting of an index sheet hereinafter more particularly described.

The worm 75 which is carried by the motor shaft 74, engages a pinion104, formed integral with a somewhat smaller pinion 105, which mesheswith the gear 91 and carries a metallic disc 106. The gears 104 and 105,together with the disc 106, constitute an integral unit, which isloosely mounted on a shaft 107, journalled inthe arms of a bracket n isconnected a clutch magnet 111, of conventional design, which is groundedto the housing 17, as shown at Gl in Fig. 8, and is adapted, whenenergized, to lock the shaft 107 to the disc 106 and thereby establish adriving connection between the motor M and that shaft. As to the magnet111, it will be noted that it is provided with a flexible lead 112,connected to a commutator collar 114, which is secured to the shaft 107but insulated therefrom, as by an insulating sleeve or hub portion 115.This commutator collar is engaged by a contact finger 116, connected toan insulating block 113, secured to the housing 17. From the contactfinger 116, a conductor 117 leads to and is connected with a clutchcontrolling brush 118, carried by the insulating support 61 andassociated with the brushes 51 to 60, hereinbefore described. Secured tothe shaft 107 is a' holding or brake disc 120, which is secured to acominutator or selector switch 121, which is insulated from the shaft107 and the disc 120 by an interposed insulating disc 122. Thiseommutator 121 includes a cylindrical metallic tube 124, provided at oneend with a flange 125, by which the commutator may be connected to theinsulating disc 122 oarried by the holding or brake disc 120. Thecylindrical tube 124 is provided with a core of insulating material 126,carrying centrally thereof a spindle 127. This spindle is connected to aplurality of radially disposed contact pins 128, the outer ends of whichare located centrally of openings 130, formed spirally in thecylindrical tube 124 and serving at all times to insulate such tube fromsaid spindle. Secured to the lower arm of the bracket 108 is a holdingor brake magnet 131, similar to the clutch magnet 111, above described,and adapted to cooperate with the metallic disc 120 to arrest rotationof the shaft 107 in a manner hereinafterv more particularly described.This magnet, like the magnet 111, is suitably grounded to the housing17, as shown at Gr2 in Fig. 8, and is connected by a conductor 132 to aholding or clutch magnet-controlling brush 134, carried by theinsulating support 61 and associated with the brushes 51 to 60.

Referring to the brushes 51 to 60, it will be noted that they engage thecylindrical tube 124 and are disposed in transverse alignment with theexposed ends of the respective contact pins 128, so that first one ofthese pins and then the next, as considered from left to right in Fig.8, will be engaged as the selector commutator is rotated in acounterelockwise direction. As to the brushes 118 and 134, however, itwill be noted that they are so related to the cylindrical tube 124 andspindle 127 as to maintain engagement therewith, respectively, under allconditions of operation.

Secured to the upper end of the shaft 107,

is a driving gear 136 which meshes with an intermediate gear 137,carried by a trunnion 138 suitably connected to the housing 17, the gear137 being in mesh with a driving gear 140, journalled on a trunnion 141,carried by a bracket 142 suitably connected to the housing 17. The gears136 and 140 are pivotally connected to a link or pitman 144, carrying anoutwardly extending actuating arni 145, which projects through ahorizontal slot 146, formed in the housing 17, the free end of the armbeing provided with a dialoperating finger 147, which projects into oneof the finger-receiving openings of the finger wheel 15 of the impulsetransmitter. It will be noted that the link or pitxnan 144 is connectedto the driving gears 136 and 140 at a distance from the respectivecenters thereof equal to the distance of the respective finger-receivingopenings from the center of rotation of the finger wheel, and that thefinger wheel, by reason of its being connected to the driving gears 136and 140 in the manner described, may be caused to rotate incorrespondence to the extent of rotation of the simultaneously operabledriving gears 136 and 140.

As hereinbefore mentioned, the individual control buttons or switches smay be singularly employed in the automatic calling of completetelephone numbers, i. e. one such switch for each such number. In orderthat these switches may so function, a lurality of records or indices I,correspon ing to a given group of telephone numbers, are provided. Therecords or indices are arranged in vertical and horizontal rows, and areconfined to definite record areas of a record sheet 148, each such areabeing ruled or otherwise marked out in Vertical and horizontal rows offield areas z" and yprovided with an elongated perforation or slot 149,adjacent the first vertical row of field areas at the left, as viewed inFigure 9. Here it is to be noted that the slots 149 of the respectivevertical rows of indices I are in alignment, and that all of such slotsare of the same length and are similarly located with respect to theseveral groups of adjacent field areas z". Also it will be noted thatthe respective horizontal rows of field areas z" of the horizontal rowsof indices I are in alignment and that the respective vertical rows offield areas of the vertical rows of indices are likewise in alignment.In making the records I, each is predetermined by a particulararrangement of a plurality of correlated perforations z', thearrangement of; the perforations in the two examples herein given beingin accord with and corresponding respectively to Barclay 2356 andCortlandt 4963. These perforations i may be made with the aid of asuitable punch or other perforating instrument, not shown, by which thenumerals, corresponding to the successive characters-both letters andnumerals-of a given telephone number, ma be punched from the properfield areas i For example, if it is desired to make a record correspondto Cortlandt 4963, the numerals 2, 6, 7, 4, 9, 6 and 3 are punched outof the first,.second, third, fourth, fifth, sixth and seventh horizontalrows of field areas This order of punching is followed because thesuccessive characters of the telephone number Cortlandt 4963 correspondto positions 2, 6, 7, 4, 9, 6 and 3 of the finger receiving openings 16that would'be successively employed in manually dialing that number. Therecord sheets 148, of which there may be as many as are required toaccommodate a given total of telephone numbers of interest to asubscriber, are .each providedy at one of its longitudinal margins witha reinforcing binder 150, having perforations adapted to receive thepins 101 of the rack 100, whereby the record sheet and consequently therecord or indices provided thereon may be automatically shifteddownwardly, as considered in Figs. 6 and 9, when the apparatus is setinto operation to call a preselected telephone number corresponding toone of the switches s. Moreover, the reinforcing binder, in cooperationwith the pins 101, serves to insure registration of the slots 149 withthe contact bars s1 at all times and to likewise'insure registration ofthe perforations i wlth 'the' proper remaining contact bars 82, s3 andso Carried by the cover or control panel 24, is an identification sheet152, on which may be provided suitable indicia by which the selectiveswitches a to j and the individual switches s may be easily identified.Asa result of easy switch-identification, the operator is enabled toquickly make a selected call, through the aid of certain of the firstgroup of switches, or a given party" call through the aid of the properindividual switch by moving it into cooperative relation to a givenindex, located below that switch and having its perforations ii so located as to characterize it according to the telephone number of theparty noted, as for example, the telephone number Cortlandt 8963 of JohnDoe, whose name appears, as shown in Fig. 1, adjacent to and identifiesa particular individual switch.

In describing the operation of the apparatus, it will be assumed, first,that the telephone number Barclay 6844 is to be called by selectiveoperation, that is, through the instrumentality of certain of theselective switches a to j: and, thereafter, it will be assumed that thetelephone number of John Doe is to be called through the operation ofone of the individual or party switches s.

To execute the first call above mentioned, the switch 66 is closed tostart the motor M, whereupon the button b is depressed to move itscontact finger 35 into engagement with the contact bar b1. As a resultof establishing contact between the Contact finger 35 and the contactbar b1, a circuit from the secondary winding 70 of the transformer 68 iscompleted by way of the conductor 71, conductor 72, cover or controlpanel 24, brush bar 34, contact finger 35, its associated conductor 41,commutator brush 52, cylindrical tube' `124, clutch control brush 118,clutch magnet 111 and housing 17 to which said magnet and the secondarywinding of the transformer are grounded. The closing of this circuitenergizes the clutch magnet 111 and thereby operatively connects themotor M to the commutator shaft 107 by reason of the fact that thismagnet, which is mounted in a fixed relation to the shaft 107, isclutched to the clutch disc Y 106 which is secured to the gear 104through the adjacent gear 105. 107 is operatively connected to the motorM, the commutator 121 begins to rotate in a counter-clockwise direction,as viewed in Figs. 5 and 8, and likewise the driving gears 136 and 140are rotated in a clockwise direction as viewed in Fig. 4, causing thefinger 147 to move or swing in a clockwise direction as viewed inFig. 1. The swinging movement of the finger 147 is utilized to move thefinger wheel 15 a predetermined distance, namely, the distance it wouldordinarily be manually moved to effect the transmittal of impulsescorresponding to the character B. In limiting the movement of the fingerwheel, it is, of course, necessary to deenergize the clutch ma net 111and thereby disconnect the motor M rom the shaft 117. Suchdeenergization takes place as soon as the commutator brush 52 disengagesthe cylindrical tube 124, but due to momentum of the commutator 121 andits associated rotating elements the commutator is carried, after beingdisconnected from the motor, a sufficient distance to establish contactbetween the commutator brush 52 and the second contact pin 128, asconsidered from the left in Fig. 8. The instant the commutator brush 52engages said contact pin 128, a circuit is closed from the secondarywinding 70 of the transformer 68 through As soon as the shaft conductor71, conductor 72, cover or control? panel 24, contact finger 35, contactbar b1, conductor 41, commutator brush 52, said contact, pin 128, thebrake magnet 131, and the housing 17, to which said magnet and saidsecondary winding are grounded. The brake magnet 131, upon beingenergized, positively locks the shaft 117 against further forwardmovement and also against return/movement until deenergization of thebrake magnet takes place under theconditions presently stated. Theoperator, upon observing that the dial 15 has been limited initsclockwise movement, as viewed in Fig. 1, releases the switch b, thusopening the brake magnet circuit at the point of contact between thecontact finger 35 and the contact bar b1. As soon `=l as this circuit isbroken and the brake magnet 131 is deenergized, the dial 15 and finger147, together with its associated elements, are returned to their normalpositions by the usual spring, not shown, of the impulse transmit- -ter14, the action of which spring is augmented by a tortion spring 175connected at one end of the intermediate gear 137 and secured at itsother end to the housing 17. In effecting the dialing of the remainingcharacters (A, R, 6 8, 4, 4) ofthe telephone number Barclay 6844,switches corresponding to the characters A, R, 6, 8, 4, 4, namely, thoseindicated by the reference characters b, g, f, h and d are actuated inthe order named, the latter being twice actuated in successiom'inasmuchas the last two numerals of the telephone number under consideration areidentical. These switches are held respectively in closed circuitposition until the forward dialing movement of the finger 147 has beenarrested. When depressing these buttons, the respective Contact arms 35are moved into engagement, with the proper contact bars a4 to jl todetermine the extent of counterclockwise movement of the commutator 121in the .manner previously described, it being noted in this connectionthat the contact pins 128, which cooperate with the respectiveoommutator brushes 51 to 61, are arranged in a spiral and are,therefore, spaced at progressively varying distances from theserespective brushes so that the forward dialing movement of the linger147 willbe proportional to the extent of movement of t e commutatornecessary to first break the circuit between a given commutator Ibrushand the cylindrical tube 124 and then establish an electrical connectionbetween that brush and its correlated contact in 128. After completingthe successive dialing operations necessary. to transmit the desirednumber, the switch 66 may be opened to stop the motor M.

In considering the operation of the apparatus with respect to a partycall to be made in response to one of the individual switches s, let itbe assumed that the party to be called is John Doe, and that the switchcorresponding to that party is located fourth from the left, and secondfrom the bottom, as viewed in Fig. 1. From an inspection of thetelephone record or index appearing in Fig. A6 and corresponding to theJohn-Doe'- switch, it will be seen that the imaginary telephone of thearty John Doe is Cortlandt 4963, the record being thus characterized byreason of the relation of the perforations z' thereof. The operator,having determined the switch to be opera-ted to call the selected party,first lifts the telephone receiver as is customary preparatory to themanual dialing of a telephone number, and then moves the selected switchdownwardly into control! ling position, Where it is held until thedialing operation has been completed. In movlthe contact bar s3,

ing the switch downwardly, a portion of the brush 36 engages the contactbar 81 through the elongated opening or slot 149 of the John-Doe-recordI, the remaining portion of the brush being in engagement with theadjacent imperforated area of the record. Upon engagement ofthe brush 36with contact bar s1, the circuit of the motor M is completed by way ofthe conductor 64, conductor 62, contact bar s1, brush 36, cover orcontrol panel 24, conductor 72 and conductor 65. The motor M upon beingset in operation so influences the governor 76 as to movethe trip lever79 to the left, as viewed in Fig. 4, thereby causing the link 84 to beretracted so as to move the worm 90 into engagement with the segmentalgear 92. Upon connecting the worm 90 with the gear 92, the gears 96 and97 are rotated in the direction of the arrows shown thereon in Fig. 2,thereby causing the rack 100 to move downwardly, carrying with it theindex sheet 148. As the index sheet continues to move, portions of thebrush 36 progressively engage certain of the contact bars 82 to authrough the respective perfora tions i', it being noted, due to thevertically spaced relations of the perforation i, that the Contact madethrough one perforation is broken before another portion of the brushengages another contact bar through the next succeeding perforation.Itis during these respective contact-breaking intervals that theapparatus'is conditioned for therespective succeeding dialingoperations, as will hereinafter moreclearly appear. As a portion of thebrush 36 with contact bar s3, which corresponds to the first characterof the telephone number Cortlandt 4963, a circuit is established fromthe secondary winding of the transformer 68, through the conductor 71,the conductor 72, the cover or control panel 24, the brush 36,

the conductor 41, commutator brus'h 52, metallic tube 124, conductor117, clutch magnet 1 11, and housing 17 to which said magnet and saidseconda winding are grounded. Energization of t e magnet 111 operativelyconnects the motor M to the shaft 107, thus causing the commutator 121to rotate in a counter-clockwise direction, as viewed in Fig. 8, and thegears 136 and 140 to rotate in a clockwise direction as viewed in Fig.4. As the gears 136 and 140 are thus rotated, the dialing finger 147 ismoved in a clockwise direction, as viewedin Fig. 1, and carries with itthe dial 15. Swinging movement of the finger 147 is discontinued as soonas it has moved a predetermined distance, namely, the distance thefinger wheel wouldvbe moved manually to transmit impulses correspondingto the character C. At or about the` time the linger 147 has been movedto the desired extent, the commutator brush 52 disengages the metallictube 124,' thereby opening the circuit of the moves into engagement finfluence of the spring 175 associated with clutch ma et 111. Due,however, to momentum o the commutator 121 and its associat-ed elements,the commutator is rotated a sufficient distance to establish contactbetween the commutator brush 52 and the second contact pin 128, asconsidered from the left in Fig. 8. The instant the commutator brush 52engages its cooperative contact pm 12.8, a circuit is completed from thesecondary winding of the transformer 68, through the conductors 71 and72, the cover or control panel 24, the brush 36, the contact bar as,conductor 41, said commutator brush 52, said contact` pin 128, thespindle 127, the brake magnet controlling brush 134, conductor 132, thebrake magnet 131' and the houslng 17 to which said brake magnet and saidsecondary winding are grounded. As the index sheet continues in itsdownward movement, the brush 36 is disengaged from the contact bar a3,thereby opening the circuit of the brake magnet 131, whereupon the dial15 of the impulse transmitter 14 is returned toits normal position bythe usual dlal-returnmg spring, not shown, and the gears 136 and 140,together with the actuating arm 145, are returned to their normalpositions under the the driving gear 140 and augmenting the action ofsaid dial-returning spring; irt- 1y after the apparatus has been thusconditioned for the next dialing operation, a portion of the brush 36engages the contact bar s?, and the dialing operation is repeated asjust described, the actuating arm 145 being arrested after having movedthe dial in a clockwise direction, as viewed in Fig. 1, equal to thedistance such' dial would be moved manually to effect the transmittal ofimpulses corresponding to the character O. From Ithe description of theoperation thus far, it will be understood that the succeeding dialingoperationsfare carried out in the order of the perforations i to movethe dial of the` impulse transmitter the proper dis- -tance for eachdialing operation. After the dialing operations, which correspond innum` ber to the total number of characters contained in thel telephonenumber, have been carried out, the `operator releases the switch a,which has been maintained in closed-circuit position during the severaldialing operations, whereupon the circuit of the motor M is opened, itbeing noted that the index sheet will have so moved as to open thecircuit of the brake magnet 131, immediately prior to the release of thedepressed switch, to permit the dial` together with its associatedoperating elements. such as the actuator arm 145 and gears 136 and 140,to return to their normal positions under the. influence of the springi753 associated with the intermediate gear 137. As the spe-cd of themotor is re duced, the governor 76 so actuated as to move the trip arm79 to the. right, viewed in Fig. 4, causing the worm 90 to disengage thesegmental gear 92, so as to permit the spring 95 to so actuate the gears96 and 97 as to cause the rack 100, together with the index sheet 148,to return to its normal position.

It is to be noted that the field areas e", into which the record areasare divided, are adequate in number, both with respect to the horizontalrows and the vertical rows of such field areas, to accommodate asufficient number of perforations to take care of or effect ten dialingoperations, although in each of the imaginary telephone numbers, hereinassumed by way of example, only seven dialing operations are necessary.In this connection, it may be remarked that the provision of additionalfield areas as herein shown, for additional perforations, is withoutconsequence, in so far as operation of the app-aratus with respect tothe index-examples herein given is concerned. This is true for thereason that should a given switch'be maintained in closed-circuitposition after the index sheet has been so moved as to break thecontactmade between the brush 36 and a given contact bar through thelast or uppermost perforation shown, no further dialing operation willbe effected, although the. motor will continue to operate so long as itscircuit is maintained in a closed condition by reason of engagement of aportion of the brush 36 with the contact s1 through the elongatedopening or slot 149. Y

As shown in Fig. 9, the elongatedslots 149 are so formed as to extend anappreciable distance beyond the uppermost row of field areas z" of therespective record areas. This is done in order to insure aclosed-circuit condition of the motor M, as between vthe brush 36 andthe contact bar s1, a suflicient length of time to lpermit the indexsheet to so move, in cases w ere an .index includes l'a maximum numberof perforations, as tovbr'eak theci-rcuit of the holding magnet incompleting operation thatwould be carried out by reason of the presenceof ay perforation in one of the field areas z" of a given uppermost row.

In order to positivelylimit the downward movement of the index sheet 148after it has so moved as to break contact between the brush 36 and anyone of the contact bars s2 to su, with which the brush may engagethrough a perforation provided in the uppermost row of field areas of arecord area, the tooth portion of the segmental gear 92 is of suchlength that the teeth of that gear Will run out of mesh with the worm 90at the proper instant. By thus severing the driving connection betweenthe Worm 90 and the gear 92, the last gear tooth, namely, the oneappearing at the right in Fig. 5, will so cooperate with the worm as toprevent the return of the gear 92 and the index sheet to their the lastdialing operation, namely, the dialing y normal positions so long. asthe circuit ofthe motor M is closed at the point of engagement ofthebrush 36 with the contact bar s, through the elongated slot-149. It willbe appreciated, therefore, that. evenA though the motor circuit ismaintained closed4 by continuing to hold the brush inclosed-circuitpositi on after the last dialing operation has beencarried out, no ill results will-.be effect/ed, .since the index sheetis arrested in its downward movement and will be elo-maintained untilthe Speeder :the motor, after opening the circuit thereof, hasdecelerated to such an extent as will enable the grnferno-i` 76 torelease the worm 90V from enga-gementwith the gear 92. f g; Althoughonly one-form of they invention is herein shown and described, itwillbeunderstoodthat various-changes may bemade withoutfdepa-rting from'thespirit of the invention or the scope of the following claims.
